Remove the code from bug #278895 since we're going to need a daemon process

in the ebuild's login session in order to pass signals from the controlling
terminal to the detached session. A simple fifo-based approach in ebuild.sh
does not seem to work since bash's read builtin occasionally loses the fifo
data when it's 'Interrupted system call'. Maybe a python script will work
better for the session leader/daemon. NOTE: The daemon will also be useful
for implementing a fifo-based die helper (to replace the current signal-
based approach).
